Post-Herpetic Neuralgia (PHN) is a painful, often debilitating condition that can persist long after the visible rash from shingles has healed. For many, it feels like burning, stabbing, or shooting nerve pain—sometimes lasting months or even years. If you're seeking long-term, drug-free relief, low-level laser therapy (LLLT)—also known as cold laser therapy—is emerging as a proven, non-invasive treatment option.
🔎 What Is Post-Herpetic Neuralgia?
PHN occurs when the varicella-zoster virus, responsible for shingles, damages peripheral nerves. This leads to:
-
Chronic nerve pain
-
Hypersensitivity or touch-induced pain (allodynia)
-
Tingling or burning sensations
-
Sleep disturbances and mood impacts
PHN is most common in adults over 50, but can affect anyone who’s had shingles. Standard treatments include anticonvulsants, topical agents, and opioids—but side effects and incomplete relief are common.
💡 How Cold Laser Therapy Relieves PHN
Cold laser therapy targets the root cause of PHN: nerve inflammation and cellular dysfunction. LLLT works through a process known as photobiomodulation, using light to:
-
Reduce inflammation in affected nerve fibres
-
Restore nerve function and accelerate regeneration
-
Enhance circulation, delivering oxygen and nutrients
-
Interrupt chronic pain signalling in the nervous system
📚 A 2020 clinical trial (PubMed ID: 32006261) reported that LLLT significantly reduced pain severity in patients with PHN, with benefits continuing after treatment ceased. Importantly, it had no reported adverse effects, making it a compelling alternative to pharmacological therapies.
🔬 How It Works: The Science Behind LLLT
LLLT uses red and near-infrared wavelengths (typically 650–850 nm) to stimulate the mitochondria—the cell’s energy centres. This boosts ATP production, reducing oxidative stress and supporting:
-
Nerve regeneration
-
Tissue repair
-
Improved neural signalling
By applying laser therapy directly to the affected dermatomes (nerve regions), users often experience reduced sensitivity, improved skin comfort, and lower daily pain levels over time.
💬 What Users Say
Many people using the Pulsed Low-Level Laser Therapy device report noticeable improvements across various nerve-related conditions, including surgical pain, inflammation, and skin sensitivity. This same mechanism is what makes it highly suited for PHN.
Users often highlight:
-
Improved mobility
-
Reduced burning and tingling
-
Less reliance on medications
-
Greater control over flare-ups
🛠 How to Use LLLT for PHN Relief
✅ Application Zones:
-
Apply directly to the affected nerve area where the shingles rash occurred
-
Target adjacent spinal nerve roots if sensitivity extends deeper
-
Don’t forget surrounding skin for inflammation management
✅ Treatment Protocol:
-
Frequency: Once or twice daily for 2–3 weeks
-
Duration: 5–15 minutes per session
-
Mode: Use pulsed light mode for deeper nerve penetration and enhanced comfort
The Pulse Laser Relief device is designed for home use, making it easy to apply consistent therapy without appointments or prescriptions.
❓ Still Wondering If It’s Right for You?
“My shingles rash is gone—why does it still hurt so much?”
This is a common and frustrating experience. The skin may heal quickly, but nerve damage can linger long after.
We’ve felt that too. And many who turn to medications for relief are disappointed by side effects or minimal pain reduction.
But here’s what we’ve found:
Cold laser therapy helps restore balance at the cellular level, giving your body what it needs to heal the nerves—not just mask the pain. And because it’s non-invasive, you can start right at home without medical risks.
✅ Why Choose the Pulse Laser Relief Device?
The Pulsed Low-Level Laser Therapy device offers:
-
Clinically relevant wavelengths for nerve repair
-
Pulsed mode for deeper, more comfortable therapy
-
Portability and ease of use
-
Trusted support from an Australian-owned company
-
A one-time investment for long-term pain management
It’s ideal for people looking for natural pain relief that works with your body, not against it.
